[dpdk-dev] DPDK techboard minutes for Apr 22nd 2020

[Honnappa Nagarahalli]

Meeting notes for the DPDK technical board meeting held on 2020-04-22

Attendees:
	- Bruce Richardson
	- Ferruh Yigit
	- Hemant Agrawal
	- Honnappa Nagarahalli (Chair)
	- Jerin Jacob
	- Kevin Traynor
	- Konstantin Ananyev
	- Maxime Coquelin
	- Olivier Matz
	- Stephen Hemminger
	- Thomas Monjalon

NOTE: The technical board meetings every second Wednesday on IRC channel  #dpdk-board, at 3pm UTC. Meetings are public and DPDK community members are welcome to attend.

NOTE: Next meeting will be on Wednesday 2020-05-06 @3pm UTC, and will be chaired by Jerin

1) Merging app/test-flow-perf in 20.05
	- This application will be kept separate from testpmd
	- It is approved to be merged in 20.05

2) Timeline to stop using rte_atomicNN_xx, rte_smp_*mb APIs (other barrier APIs, rte_*mb, rte_cio_*mb, rte_io_*mb, are allowed to be used)
	- The formal deprecation of these APIs, which affects the DPDK applications, is postponed to a later point
	- It was agreed to stop accepting new code with the above APIs after 20.05 release
                (subject to the availability of the patch for wrappers for C11 atomic built-ins) - AI, Honnappa
	- Add a note in the release notes to indicate the same - AI, Honnappa

3) Wrappers for C11 atomic built-ins will not be available for 20.05. Patches using C11 atomic built-ins will be accepted for 20.05
    (as there is already lot of code with C11 atomic built-ins)

4) Need volunteers for maintaining C11 code
	- This role is to support the maintainers with questions, help debug issues
	- It would be good to have one maintainer from each supported architecture, volunteers are needed
	- Honnappa is the maintainer from Arm

5) Ask Windows team to build and test with C11 code enabled in CI (for ex: rte_ring) - AI, Thomas

6) Multi-function chaining APIs
	- A conclusion could not be reached. The discussion/voting is still ongoing. I will post the update once the decision is done.

Thank you,
Honnappa

Tech-board made a decision to accept a temporary solution for 20.05. The choice of the solution will be made on the mailing list.
Please document this as a temporary solution and will be replaced with a permanent solution when one becomes available.
